GUMMED-BLANK AND UNWBAPPED-BOX REGISTERING MECHANISM.

Application filed February 8, 1916.

To all whom it may concern Be it known that we. M'nm'imm E. Purses, Gnoncn H. FA'rn, and Annrnrr F. Mmnun, citizens of the United States of America, residing in the city and county of Denver and State of Colorado, have invented a new and useful Gummed-Blank and UnwrappedBox Registering Mechanism, of which the following is a specification.

Our invention relates to a. gnmmed blank and an unwrapped box registering mechanism for blank and label gumming ma chines, in which means is provided for gluing the bottoms of paste-board boxes of either the stayed corner type, the unstayed corner type, or the extension edge type of unwrapped or uncovered paste-board boxes directly to the gummed surfaces of the blanks, as they. are gummed in a gumming machine and are conveyed away from it after being coated with any adhesive gum or glue; and the objects of our invention are:

First, to provide means for gluing boxes directly to gummed blanks as they feed from the gumn'iing mechanism.

Second, to provide means for conveying the gmmned blanks to a predetermined point by a suitable conveyor and then picking them off of the conveyor and feeding them, foruuud to the top of a suitable table, which is arranged to permit the box to be glued directly to the gummed blank. And

Third, to provide a rapidly operating directmanner of adhesively attaching the bottoms of paste-board boxes to finishing blanks or labels, that enables the boxes to be accu rately centered on their covering or wrapping blank or labels at the time and in the same machine they are freshly gunnned in, and as they feed in one continuously feeding movement through the gumming lnachine.

We attain these objects by the mechanism illustrated in the accompanying drawings. in which:

Referring to drawings,-

The numeral 1 designates a fragment of rear view of .one end of the M the supporting frame of our invention. The

fragment of the frame illustrated is the-rear or discharging end of the frame of the gumming machine. This frame consists of. two side frames 2 and 2 spaced at sufficient distances apart to receive most of the machine's mechanism between them. These side frames 2 and 2 rest on and are secured to a base plate 3, and a cross brace bar -.t is extended between these frames and extends through and is bolted to them to rigidly secure them together. The rear end of. each frame is provided with a rearwardly extending arm 5, that supports a cross bar 6 that extends from one side frame to. the other. This cross bar is provided with longitudinal slots in which sliding clips 7 are fitted that are :uljustably clamped in the slots and to the cross bar by cap screws 8. These sliding clips 7 are provided with rearward extensions 9 that are adapted to form box end' guiding clip 10 is secured to the center of the crossbar. These three box guiding eli s are curved rearwardly at their up er en s, so that the boxes can be quickly p aced between them without striking their upper edges. f

The machine and its gumming mechanism, as well of the blank receiving end of the con veyer, are fully illustrated in our pending application Serial h'umber 30,471, filed May 25, 1915, for a pneumatically controlled and automatically operating blank gumming and tempering machine.

In that pending application the blanks are fed to ablank feeding roller, and this feed roller feeds them to a gumming cylinder, from which they are transferred to an encl- -less conveyer, the end of which that lies adjacent to the gumming cylinder is supported by sprocket wheels, and the center of the conveyer which is provided with blank supporting aprons'runs over a gapped cylinder which we term a transmission cylinder. This. conveyer has an intermittent movement and it stops long enough at its reverse turning point, which is marked by an arrow which point we call its stopping or discharging station. We do not illustrate the mechanism that intermittently starts, runs and stops this endless convcy'er, as it is-controlled by the rotary movement of the gumming cylinder, and is illustrated in the above mentioned a plication.

Each-blank supporting a ron of this con- 'veyer is provided with a pl gripping fingers, which enters the gap of the transmission cylinder as the aprons rotate and theyare positioned to ,grip each blank 'by its forwardly feeding edge as it is coated with gum by the gununing cylinder, and peel. itoftfrom the gummlng cylinder onto its adjacent apron against the topsurface of j whichthe blank feeds out flat or as the of the transmission cylinder.

The aprons with the blanks on them travel in a straight horizontal plane from the top of the transn'iission cylinder to its stopping station. fromwhich pnint it runs over apron turns up over the periplieral surface he blanks k urality of blank edge ofthe apron and through the bars.

sprocket wheels 12 and a roller 14 and then down and back to an idler supporting member and then up to the transmission cylinder. The above brief descriptjpn is'all that is deemed necessary of theblank feeding gumming and the blank receiving end of the endless apron conveyer that delivers the blanks to the airgripping tubes'of our boxand blank registering mechanism.

Our present invention does not appertain to the blank feeding or gummin mechanism; Consequently we deem it su cient to say that the blanks are properly gummed and are fed onto the conveyer, and are delivered to apparatus which we will presently describe that transmits them one at a time onto atable where an attendant can place a box directly and centrally on top of and against the gummed surface of the blankf Instantly afterward the blank with the box adhesively fastened to it, is fed into engaging relation to the upper plunger of a box wrapping machine. The conveyer consists of the oppositely arranged side chains 11,

which are mounted on sprocket wheels 12 that are secured on the opposite ends of a shaft 13, on which a roller 14 is mounted and secured.

A bar 15 is placed across and between the sprocket chains, the opposite ends of which 9 are secured to the sides of the links they are a placed between.

This bai' 15 forms the advance feeding end, which is the end that is traveling for ward to convey the blanks from their gumming mechanism to the discharging end and stopping station of the conveyer and of the blank supporting aprons 16. These aprons are preferably made of rubberized cloth but may be made of any other suitable material. They 5 aremadewide enough and long enough to support on their top surface the largest size blanks-the gumming machine will apply a coat of adhesive gum or glue to. Their advancing edge is secured to the bar 15 by a clamping strip 17,.thatis seat l in a stepped recess 18, that is preferably inclined downwardly and forwardly from the top'surface of the bar. The clamping strip is secured to i the bar by flush headed screws 19, which when loosened permit the edge of the apron to be tucked under it. The edge of the apron 1s then clamped by the screws and strip against the inclined stepped portion of the bar, The opposite 'end'of each apron is seme cured to a bar 20, that extends across and 1 between the sprocket chains of the conveyer, and is secured to thelinks of the chain it is placed against. There are a number of ways of securing the rear end of each apron to its supporting cross bar, but we preferably lace 1 thisend of the apron to these erOSsbarsby a lacing 21., which is laced throuh suitably formed apertures formed both-t rough the i The lacing permits the apron to be stretched tightly between .its supporting bars, and to be tightened and adjusted from timeto time as it stretches. There are preferably nine of these aprons in the length of this endless conveyor, and they are spaced at a distance apart that will allow them to receive the blanks from the blank gumming cylinder of the machine.

The top of the bar 15 is provided at intervals across its length with thin disks 29., which are provided with stem portions '23 that are inserted in thetop of the bar so that the disks rest flat against thetop of the bar. These disks make raised fiat round points for the advancing or forwardly moving blanks to rest on, as will be presently described.

Two rows of these disks are provided, one row being ofi'set slightly to one side of the other, and the disks of one row are preferably set close to the disks of the other row,

and both rows are of the same height. y The top of each disk in one of the rows of disks is engaged by a finger gripper 24:, which grippers are arranged to grip and clamp the edges oieach blank to them, a row of which is provided, as will be presently explained, while the top of each disk 25 in the row of disks is engaged by an air suction tube 26, a row of which is provided, askwill be presently explained.

Each gripping finger in the row of blank gripping fingers is pivotally mounted in a block 27 which ismounted on a square bar 28 that is mounted at its opposite ends in lugs 29, that project from theblank gripping side of the cross bar 15. The blocks 27 on this blank gripping finger supporting bar are provided witlr recesses in which a lag portion 30 of each finger is placed. The

ottoms of each of these recesses are beveled downwardly fromthe top surfaces, and.

a pin 31 is, extended entirely through the block and loosely through the lugs of the blank grippers. Each blank gripper comprises a central body portion, from the bottom of which the lug depends. This central body portions extends into ablank gripping flat finger portion 24: that terminates in a end on its under side that engages and rests on top of its adjacent disk, This central body portion also extends in an opposite direction from the blank grippingfinger and terminates in an end the under side of which engages the top end of an expansive coiled spring 32 that is seated in a hole 33 formed in block '27 on the bar 28 to receive It. This expansive spring 32 has a tendency to 'norm'ally hold the end 3i of top of its-respective disk.

the finger up, and the end 35 0f tho'finger down wlth a. resilient tension against the Consequently when they are moved to gripablank against the disks 22 they do so with a backwardly yieldingresilient pressure. The bar itself to which these blank gripping clips are piv otally connected extends rotatirely through its lugs at both ends. and at one end beyond the lug a disk 36 is secured on it. and secures this bar against lateral movement in itslugs. The peripheral edge of this disk 36 is provided with a ratchet toothed lug 38 which is adapted to be engaged by a paw 39 when the blank gripping lingers are raised to release each blank at the blank releasing and the stopping station of the con vcyer, as will be presently explained.

This pawl is a rock arm pawl and it is pivotally attached to a projecting portion 40 of he bar 15, by a pin ll that projects beyond the projection vt'ar enough to receive a coiled spring 42, one end of which is at: t'ached to the lug 40 and its opposite end is secured to a collar 43 secured on the pin. This spring is arranged to hold the toothed end of the pawl with a resilient pressure against the peripheral surface of the disk. while the tooth 43 of the pawl is arranged to engage the tooth of the disk when the disk is turned far enough around by the upward and backward movement of the fingers.

The'bar 28 is provided on its opposite end portions inside of its supporting lugs with reduced portions, on each of which acoiled expansive spring 44 is mounted; one end of each of these springs projects into apertures in the lugs and is thus secured to them, while. the opposite end of each spring is secured to a collar 45, that is loosely mounted on the reduced portionof the bar. Each of these collars is provided at four diametri cally opposite points with slots, and a pin 46 is secured to each of the reduced portions of the shaft adjacent to the slotted end of its collarand the slots in the collars fit loosely around its adjacent pin, which becomes a tightening and locking pin for the collar.

The expansive tension of the spring holds the collars when one of their slots surrounds the pin against it by a longitudinal thrust, while the pin locks the collar and spring against. a turning movement.

These springs are adapted to exert a down wardly turning throw movement on thebar and a yieldingpressure relief movement to the fingers when they are released from the pawl, which is accomplished by a cam, at

' that point of the conveyers traveling move ment which is at the blank gumming and transmission cylinders of the machine.

The gumming and the blank transferring mechanism that operate to grip each blank as it is coated with gum, onto the" trans- 125 ing application;

' lies on its apron, and instantly before these These blank gripping fingers are automatically raised to release a blank by a segment gear 47 that is arranged and operated as follows:

On the opposite end of the finger engag ing bar from the ratchet toothed disk, a segmenttoothed pinion i8 is secured that contains gear teeth on its periphery, and these teeth as the coni'eyer chain comes to a stop, are in position to be engaged by the teeth d9 of the toothed segment lever 47 that lies in the traveling path of the segment toothed pinion 48 of the bar 28. This segment toothed lever is mounted on the shaft 13 that supports the conveyers sprocket wheels, and its roller, on which the conveyer turns. This segment toothed lever is pivotally connected to one end of a link 50, the opposite end of which is pivotally secured to one end of a bell crank lever 51, the other end of which is attached to a connecting rod 52, the opposite end of which is pivot-ally connected to one end oi a rock ann which is pivotally attached intermediate of its end to the frame ofthe machine.- The opposite free end of this rock arm is provided with a roller 54: that projects into a cam runway track that is formed in one side of a disk that is mounted on a shaft. 56.

This segment toothed pinion is engaged by the segment tooth lever just after the bar with the fingers gripping a blank to it, reaches the stopping station of the conveyer, and the cam actuated levers pull the segment toothed lever to rotate the segment pinion just after the tubes 26 have engaged the edge of the blank.

This partial rotating movement that the segment lever imparts to the segmentpinion, turns the blank gripping finger bar in a,

direction that swings the blank gripping finger upward and backward far enough to instantly release the gummed blank, as it fingers are raised up the air inlet suction tubes 26 are moved down on top of and against the blank and the disks upon which the advance edge of the blank still rests, and

these tubes bear against the blank and. disk which insures that each tube. will have a firm bearing against the blank.

, forwardly a short distance and deposit it on a reciprocating able 57, which instantly grips the blank by air suction. The table then carries the blank forward under the box guiding clips 9 and 10, andthensto'ps long enough for an attendant to place a box directly on and press it down firmly I of the box.

and evenly against the gum coated central body portion of the blank, which adhesively sticks and secures the blank to the bottom Then instantly after the attendant lifts the box within the blank firmly glued to it off from thetable and transfers it by hand to the up! plunger of, a box Wrapping machine, unich we do not illus trate.

Our preferred construction of the mech- 'anism that accomplishes these functions is as follows, although our invention contemplates any and every and all means by which they can be accomplished:

To the side frame 2 of the machine,ia vertically reciprocating bar 58 is ,slidably mounted in guideways 59 and 60 that are formed on the side frame. This frame is reciprocated by a cam groove (51, that is enportion that is formed on the lower end of:

the bar. This vertically reciprocating bar extends above the side frame 2, and at its upper end it is provided with a cross bar portion 63, which forms a slide'way. A cross head 64 is slidably mounted on the slideway of the cross bar. This cross head is provided with a laterally extending hub 65, that ex tends at'right angles to the longitudinal axis of the machine and toward the opposite sic e frameQ and a tubular bar 66 extends into it and is rigidly secured to it. This tubular shaft has an axial aperture that extends from its inner end to near its opposite end. Both ends however are plugged up and an air inlet aperture is made through the hub 65,- and through the tubular shaft, into it. This tubular shaft extends over the roller on which the aprons of the conveyor turn,

and they are positioned to move vertically. and reciprocally abo e and toward it a distance suflicient'to allow its air suction tubes to grip and lift the blanks and-oarry them above and deposit them on the table 57. Each of these blank suction gripping tubes is mounted on the tubular shaftiand has a slight turning movement thereon that gives each tube a pressure-relief'movement independent of the-others. We preferably illustrate six of these air suction tubes, although a more or less number of them may be used if desired. 4 v

Each of these air suctiontubes comprises a tube holding. stem 67 that is provided with a hub' 68 which is loosely mounted on the tubular shaft, and is held thereon by a pin which extends loosely through an aperture in the hub to receive it,-which aperture is made enough larger' in" diameter than the,

pin to allow the hub audits stem a turning movement on the tubular shaft of about an eighth of an inch. The stem 67 is provided. with a rearwardly extending lug portion 69 through which a screw 70 is threaded to top end of the screw is aperture 78.

stand vertically. A horizontal screw 71 passes through a slot in the hub 68, and is screwed into the tube 66, and a coiled expansive tension spring 72 is mounted on the pin at one end and bears at its opposite-end against the outer end of the screw 71. The rovided with a screw driver slot to enable it to be turned to adjust the pin 70, which carries awasher 7 that bears uponthe top of the spring, so that the tension of the spring may be varied A nut 72 is also threaded to the screw and is turned against the top of the lug to lock it in adjusted positions. Each tube holding stem isprovided with a ver-, tical lug member at its outer end that provided with a vertical aperture in which,

the tubular member 26 1s slidably mounted.

'lhese tubular members we term the air suc-.

tion tubes, and they are each adjustably secured in its respective vertical shdeway by a set screw 73. Each of these air suction tubes is provided with an axial bore 7%- that extends into its lower end to near its top end, and an aperture 75 is formed through its side. The stem 67 is also provided with an axial aperture 76 that registers at one end with the side aperture in the tubular member '26, and at its opposite end with an aperture 77 that is formed through the adj acent side of the tubular shaft into its axial The upper end of each air suction tube provided with a knurled surface that enables the tube to be easily held by the fingers of an attendant. As the air inlet ends of these air suction tubes are constantly engaging the gmnmed surfaces of the blanks, they are each slightly coated with gum when the-v release a. blank on the table, and it is ncc any that some means be employed to wipe or washtheir ends in order to wash off from them any moist gumthat may be on them. There are a number of ways in which this feature of our invention can be carried out. l ve preferably however construct andarran'ge this feature of our invention in the following manner, although our in vention contemplates all means by which the ends of the air suction tubes of our invention canlie cleaned after depositing each blank onits box applying table and picking up another blank: from the conveyor.

Across the machine from one side to the other, and at right angles to the longitudinal axis of the machine, we mount in bear- 'ings a shaft 7 9 to which an oscillating rocking motion is imparted by a cam actuated lever mechanism, which consists of a lever 80 that is secured to one end of the shaft, to the outer end of which a connecting lever 81 is pivotally secured, the opposite end of which is pivotally connected to one end of a rock arm 82, which pivotally connected to one end of a spindle 82/5. The opposite before end of this spindle carries a rock arm which is provided with a roller 83, that projects into an inclosed runway cam which isformed on one side of a disk 81 that ismounted on the shaft 56 that is driven by any suitable rotary power transmitting means from the main drivinq shaft, which power transmission means we do not illustrate.

Upon the oscillating movement shaft 79 we mount and secure a plurality of..:irms 85, the number being the same as the num-' ber of air suction inlet tubes lar shaft, and each arm secured on the oscillating shaft opposite to one of the air suction tubes.

is positioned in alinement with and in the path of the rearwardly moving air inlet suction tubes at th upper endportion of their reciprocal swinging oscillating stroke movement." Directly below these arms and in their swinging movement path, a pan 86 is secured to a bar 87, which is secured to the frame work of the machine by screws 88. This pan isprovided with a supply of water to a sufficient depth to fully immerse the roller 89, of the arms at the end of its downward stroke movement. lonsequently the rollers which are arranged in alinement across the shaft 79, are-- all dipped into the water as each blank is fed forward onto the table 57 and their rollers are swung up by their actuating cams into the path of the blank engaging ends of-thc rearwardly moving air suction inlet tubes, which the ends frictional pressure against the surface of the rollers that will effectually wash and clean and wipe the blank engaging ends of the air inlet suction tubes. The air suction tubes and their supporting cross head are recipro- Each of the, arms is provided with a roller 89 at its free end, which 26 on the tubucated in a horizontal plane in connection with their joint raising and lowering movement by the arm actuated cam and lever mechanism, by a train of gearing, which is actuatedby a .cam actuated lever mechanism, and this cross head and air suction inlet tube reciprocating mechanism comprises the followin instrumentalities:

U on the back 0 the reciprocating cross hea a toothed rack 90 is secured in which a pinion 91 meshes. This pinion is mounted on one end of a vertical shaft 92, and as this pinion is rotated. in reverse directions it reciprocates the cross head in opposite directions on the bar 63. The opposite end of the shaft 92 extends to near the base sli'dably is rough a corresponding aperture v through which the bolt passes.

in a pinion 93, which is rotatably mounted in suitable bearings 94, secured to the adjacent side frame. The pinion 93 meshes with a toothed rack portion that is formed on one end of a bar 95 that is reciprocally mounted in suitable bearings 96 that are secured to the frame Work of the machine. The opposite end of this bar is also provided with a toothed rack portion 97 that meshes with a pinion 98 that is mounted on one end of a stub shaft 99 that is rigidly mounted in a suitable bearin 100 that is secured. to the bed plate 3. 1 gear 101 is secured on the hub of the gear 98,- and this gear meshes with a. toothed rack portion 102 that is formed on one end of a rack bar 103 which is slidably mounted in a suitable bear ing 104 that forms art of the bearing 100. The opposite end 0 this rack bar is pivotally connected to one end of a link 105, the opposite end of which is pivotally connected to one end of a lever 106, the opposite end of which is pivotally secured to a shaft 107 which is supported in the frame of the machine. A roller 108 is pivotally secured to this lever intermediate of its ends, which projects into an inclosed cam runway track that is formed on one side of a cam disk109 that is mounted on the shaft 56, which rotatively drives the cam and the cam reciprocates the lever 106 and the lever through the medium oithe link 105 reciprocates the rack bar 103 which rotates the gears 101 and 98 and the gear 98 drives the rack bar 95 which rotates the vertical shaft 92 and its upper pinion reciprocates the cross head and the air suction tubes, from the stopping station ofthe conveyer, where they pick up a blank to the top of the table 5Tr where they deposit it, as will be presently described.

The blank receiving table rectangular shaped fiat'piece of any suitable material. preferably aluminum, which is secured at its opposite sides to tooth rack bars 110, that are reciprocally mounted in suitable guideways 111. that are formed in bars 112 that are secured to the opposite ide frames of the i'nachines. The gear teeth of these rack bars 110 are engaged gears lll'l'that are secured on the opposite end portions of a shaft 111 that extends transversely across the machine and is rotatably journaled in bearings formed on the side'frames. pinion 115. is also secured on this shaft which engaged by the gear teeth of a vertically positioned rack bar 110 which reciprocally mounted in bearings 11? that are secured to the adjacent side frame. The lower end of this reciprocating bar-is provided with a slida'liily and adjustably bolted by a bolt in a slot 11.) that is formed in the bar. The block 118 is pivotally secured to one end of the bar 120 and to the other end of this bar one to a position centrally consists ot' a by two block 118 that (and of a lever 121 is' pivotally secured.- The opposite end of this lever is rigidly connectedto a short shaft 122 which is pivotallymounted in the frame, and a lever is secured upon the opposite end'of the shaft 122 to which a. roller 123 is pivotally secured and is arranged to extend into an inclosed cam runway track that is formed on one of the sides of the cam 84, which is se cured on the shaft56. The cam as it rotates causes the lever to reciprocate the vertical rack bar, which causes the pinion 115 to rotate the the gears 113 to reciprocally move the table supporting rack bars 110 and consequently the-table. As illustrated, the table is at the end of the outer stroke of its reciprocal movement, and the air suction inlet tubes on the backward stroke of their reciprocal movement have traveled to a pointwhere they engage their wiper rollers. When in operation, these air suction tubes move back above the roller 14 shaft 114 and its gears 113, and.

and when in that position the rear edge of the table moves back to the dotted line A. The air suction tubes receive the air suction force from an air pump 124 that is mounted on the base plate of the machine, and this pump is operatively connected by a hose to an air inlet aperture that is formed in the hub 05 of the cross head that connects with the axial-aperture of the tubular shaft 06, The air pump's piston rod is pivotally connected at its outer end to one end of a lever 123, the opposite endof which is pivotally mounted on the shaft 107 and this lever is provided with a roller intermediate of its ends that projects into an in closed cam rumvay track that is formed on one side of the disk 109 that is mounted on the shaftfifi.

'hen the table has griy ped a blank and fed it forward to the limitot' the forward stroke of its reciprocal movement, it stops for a lew seconds before it starts on the rearward stroke of its reciprocal movement, and an attendant places a box between the guides and against the guide 10, which are positioned to allow the box to be placed centrally over the central body portion ot" the gummcd side of the blank. when it is the table and is placedby hand on the upper plunger of a box wrapping machine, oi. which there are-a number An improved box wrapping machine that is especially adapted to be used to receive the boxes avith their labels attached, illustrated in our pending application Serial. Nnmbe' 59,860, filed November ii, 191:"), for an automatically operating multiple stage box wrapping machine.

The operation of our blank and box regisgumming machines, is as follows:

The blanks are fed on the aprons in a continuous and successive straim to the conveyers stopping and blank dischaiging station, and then each blank is gripped at its advance edge portion, and is picked up by the air suction tubes 26 and is lifted up above the table and is carried forward by these tubes to the front edge of the table. The place the edge of the air suction inlet a wrtures of the table, and press its edge against them and instantly after the tables air suction inlet apertures grip the blank the tubes release it while the table holds it and the body of the blank liesgllat on the table. The table then moves forward under the box guiding clips and stopsthere for a few seconds, and the instant it stops the attendant quickly places a box between the guide clips and presses it down evenly and firmly against gummcd surface of the central body portion of the blank, and then instantly removes the. box from the table. The box has the blank adhcsively sticking to it, and the attendant then takes it and places it on the machine, which should be "positioned close enough to the gnmn'iing machine for the attendant to make this transfer quick enough to be ready 2 side of the blank, a

to place a box on the next blank that is fed out by the table in box receiving position, as instantly after the box and blank are .removed from the registering table, the table, is moved back in position to receive another blank from the air suction blank lifting and forwardly feeding tubes.

'lhe'various mechanisms are adapted to be changed to fit boxes of all sizes, ranging from about 2x4: to 12x20 inches in size and of varying depths.

Having described our invention, what we claim as new and desire to secure by Letters Patent, is:
